"David has been an excellent laboratory director to work with, as I have strived to make advances in the field of acoustics. His personality makes it easy to discuss openly the measurement data acquired. He is always willing to discuss the data with me and then troubleshoot and try new things. He runs an effective laboratory that can output quite a bit of measurements/data in relatively little time. He is always honest about his laboratory's capabilities and his analysis of the data. His laboratory has been one my greatest assets in furthering research and development in acoustics."

"We recently contracted with North Orbit Acoustic Laboratories for an evaluation of our worship space. We had many questions about improving our room acoustics. NOAL was the solution to our questions. They arrived at our site and measured reverberation time, frequency response, and speech intelligibility. Their report was complete and thorough. We are more than pleased. Their work was professional and easy to understand. I highly recommend them for acoustic needs."

"Getting the sound right in my studio was my highest priority. NOAL came in, gave me a proposal, worked with me on my design choices then guided me through to completion. They are informative, knowledgeable, efficient, flexible and creative."
